 Taking a further step back we've taken a very simple auction contract and transformed it into a more production contract with thorough testing. To improve the auction we learned how to make a contract more secure by locking it, added a prize by introducing NFTs, and enabled auctioneers to host auctions with FTs.

-Whilst we can see the highest bid we may want to see the auction's bidding history. Since the contract only stores the most recent bid we need to use an indexer to pull historical data. In the [next part](./6-indexing.md) of the tutorial, we'll look at quering historical data using an API endpoint.
